This paper investigates the rise of South Korean tourism in the Philippines from 2014 to 2018 and explain its behavior year-to-year, and the other part is to forecast it’s growth or decline in the next following years; all of this is done through a Seasonal ARIMA (SARIMA) modelling framework. Results reveal that Korean arrivals were best modelled through a ARIMA(1,0,0)(2,1,0)₁₂ model, with residuals that are randomly distributed and contain no autocorrelations and an AICc value of -36.18, the lowest among the tested variations of the model, the model is the most appropriate to forecast the data for a 3-year period.

This study proposes a nonparametric bootstrap-based test to compare performances between two portfolios in terms of their information ratio. This serves as an extension to the literature that tests performance between two portfolio investment strategies that uses Sharpe ratio. Monte Carlo experiments show that the test has appropriate sizes and is powerful to most of the scenarios. However, the test does not perform well in highly correlated portfolio returns, but is better when the mean of portfolio return is modeled using an autocorrelated process.
